My case is a bmp unzipped to a 4-byte aligned address. The two signature bytes of the bmp header make the other fields 4-byte unaligned. We could force unzip the bmp to an aligned address + 2.

Is this a better solution?

That is the solution we settled on the last time this was discussed. See CONFIG_SPLASHIMAGE_GUARD in the README file if your use case involves user input, or just pick an aligned address + 2 in your code.
